The problem as always with such services is that they are all about monetisation of the userbase, any reason they can think of to gather further current data on their users will be taken, I hate to state the obvious but its not much more than we have the capabilities for on this network, in thier model each user or group is a "channel" and you can toss images or video into the channel or indeed many channels.
I am still in wonder regarding just how much the share price of this entity is considering it delivers so little bar its popularity, when the folks using it wake up to the fact that they have been keeping "facebook" fat on their information and recieve a diminishing need of the service they may just come to the realisation of the true price they have paid for losing their privacy across so many years, its not just your folks and friends whom have access to your data.
